ATTACHING CLIP.

Application filed April 15,

My invention relates to an improved attaching means, or clip, forfastening fountain pens and other articles of a similar shape or natureto the sides of pockets or to the edges of garments, and aims to providea clip having a maximum -of effective gripping surface,

and easily manipulated without damaging the garment.

@ne object of the invention is to e'ect the claspng pressureperpendicular to the thickness of the material engaged, free fromwedging or bunching effect thereon, and hence free from forces weakeningthe hold of thegripping members on the material by tending to push thelatter endwise.

A further object is to provide a clipv which may be readily adjusted toengage with equal effect any one of a wide range of thicknesses ofmaterial, and which may be readily released from said engagement withoutthe necessity of pulling the material from between the opposed grippingmembers.

For convenience I show and describe my clip in conjunction with afountain pen cap, although it is equally applicable to any object of thesame general shape which one may desire to attach removably to the clothof a coat pocket or the like. For example, my improved clip is intendedfor use with pencils, clinical thermometer cases, spectacle cases and soon, as well as fountain pens.

lllustrative embodiments of my invention are described in the followingspecification and in the accompanying drawings, wherein Fig. 1 is alongitudinal central section of a fountain pen cap showing one form ofmy improved clip in connection therewith, showing` the clip in retractedposition;

Fig. 2 is a view similar to Fig. 1, but illustrating a modified pivot,the clip being in extended position;

In the embodiment illustrated in Figs. 1 to 5, inclusive, the clipconsists of a finger 1 disposed at right angles to a head 2', said headbeing slotted as at 3 and provided at the end opposite said finger withan upstandinglug 4, all preferably integral. Said finger may be formedwith a re-entrant bend 5, preferably near the free end, for more secureengagement with the material to which the cap is to 'be fastened. The caused in connection with this embodiment is flirmed with top and siderecesses 7 and 8. The head 2 slides in and out in the top recess 7, andthe linger 1 may be fully retracted within recess 8, which is suitablyhollowed out to take the bend 5, thus avoiding any projections above theside surface of the cap. A top 9 is rotatably attached to the upper endof said cap by suitable pivot means, such as shown at 10, Fig. 1, or 11Fig. 2, passing through the slot 3 in the head 2.- Said top is spirallygrooved, as at 12, in its lower face to engage lug 4 of the head. Thuswhen the top 9 is turned the travel of the lug 4. in the groove 12 willmove the head 2, varying the distance between the 80 linger 1 and theside of the cap. The finger 1 in-all positions will be in the sameangular relation to the cap, preferably parallel there-A to, because ofthe mutual rigidity of the finger 'f and the head 2. e5

In Figs. 6 to 11 inclusive I illustrate forms of my invention whereinthe finger is normally held within the side recess of the cap byspringaction and is adapted to be moved outwardly by thumb pressure.

ln the form shown by Fig. 6 a single strip of metal is bent as shown,forming a linger 13, similar to the finger 1 of Fig. 1, a cross memberor head 14 adapted to slide in a guide-hole 15 in the cap, an axialshank 16, passing through c5 the end of the cap, a button 17, and allshaped spring 18 the lower end ofwhich rests upon an inner end 19within the cap. l

Fig. 7 illustrates a modification having the cross member or head 20 inthe form of a bow ma spring arranged to be pressed by a stem 21 carryingan-external button 22. The spring cross head 20 is stopped on one end bythe barrel of the cap, while the opposite end passes through a guideway15, and is externally joined to the linger 13.

Pressure on the end button in the modifications illustrated by Figs. 6and 7 causes the cross head to move outward through the guideway,carrying the finger away from the ma cap in an obvious manner. Theguideway forces the close head to move outwardly without tilting, sothat the finger is maintained parallel to the side of the cap.

Figs. 8, 9 and 10 illustrate further spring forms, all used inconnection with a clip wherein the cross head is straight and transverseto the cap, projecting therethrough on the side opposite to the fingerand there ter.- minating in a button 17 The springs 2 3, Fig. 8, and 24,Fig. 10, are of theaccordion type, integral with the clip structure. Thespring 25 in Fig. 9 is coiled, bearing at one end against a cross member26 secured to the clip head and at the other against the inside of thecap.

Fig. 11 shows an' additional modification, of the forms disclosed byFigs. 8, 9 and 10, but having the inner end 27 of the clip head turnedupward, inside the cap, engaging one end of the spring 28. This upturnedend 27 passes upward through and is adapted to move in a diametral slot29 in the cap cover 30 and carries an irregularly T-shaped guide member31 which covers the slot 29 in one direction, projects slight-ly overthe side of the `threads 34 stop short of the top of the cap so as toprovide a chamber between the outer end of the cap and the end 19 of theplug for the reception of the spring and the clip head. It will beunderstood that the inner end 19 need not necessarily be constructed andinserted as above described, but for example, may be formed integralwith the cap, as illustrated at '37 Bin Figs. 7, 9, lO'and 11, orconstructed in any suitable manner.

A preferred cap end construction for use in conjunction Awith any of myabove described spring-actuated clips, is shown in Fig. 12, wherein areduced externally threaded end 38 of the cap barreltakes an internallythreaded cover, such as 39, Fig.,10. The reduced end is slotted, as atL10-41,.for the reception of the clip head,- which is held in-place bythe cover 39. The side of the barrel is recessed as at 4.2, forming aseat for the linger 13. It is intended that Fig. 12 be considered as inthe nature of a diagrammatic showing, and that certain features thereofyare to be understood as subject to appropriate modification to suitvarious forms of spring, as particularly illustrated in Figs. 6 to 11inclusive. Thus a cap for use with the spring shown by Figs. 6, 7 and 11will be provided only with the slot 40 while the depth of the threadedend 38 will be less in connection with such springs as are illustratedby Figs. 9 and 10 than with those shown in Figs. 6, 7, 8 and 11.

To slip the pen into engagement over the edge of a pocket or the like,the finger is moved far enough out to admitthe cloth loosely between thefinger Iandthe side of the cap without wear on the cloth. The cloth isthen tightly gripped by retraction of the finger. rlhe engagement isreleased in the reverse order, and the finger afterwards retracted intoits recess, whereupon the cap presents an exterior surface free fromprojections.

The feature of having the finger always parallel to the side of the capgives a very secure hold by reason of the fact that the inner surface ofthe finger and the entire opposed surface of the side of the cap bearwith substantially equal .force upon the cloth gripped between them.Further security particularly in gripping thin materials, results fromthe binding effect between the reentrant bend 5 and its correspondinghollow. As distinguished from this parallel and even grip, the usualtype of clip, which is either rigidly or pivotally secured .to the cap,holds the cloth by a wedging action which includes a force componenttending to slide the cloth out of the wedge. With thin cloth this`results in a hold only close to the apex ofthe wedge, while with a thickcloth, such as overcoating, the clip finger is sprung out so far thatlthe sliding component is pronounced. As a result it is almostimpossible, practically, to fasten a fountain pen having the usual typeof clip securely to such thin material as that of a silk shirt or tosuch thick material as that of an overcoat, particularly if the pen beplaced at an angle on an edge of the garment instead of hooked over thetop of a pocket. j
